APPARATUS FOR DYEING, 86C.

SPECIFICATION forming part of Letters Patent No. 509,431, dated November 28, 1893.

Application filed November 7, 1892- Serial No. 451,167. (No model.)

To wZZ whom it may concern.-

Be it known that we, AUGUST GRAEMIGER and JOSEPH GRAEMIGER, citizens of the Republic of Switzerland, residing at Edenfield, near Bury, in the county of Lancaster, Kingdom of Great Britain, have invented certain new and useful Improvements in Apparatus tor Dyeing, Scouring, Bleaching, and otherwise Treating Yarn in Cop or Similar Form, of which the following is a specification.

Provisional protection has been secured in Great Britain under application filed Septem her 8, 1891, No. 15,174.

This invention relates to that class of apparatus for dyeing, scouring, bleaching and otherwise treating yarn in cop or other similar compact form, in which it is placed on hollow perforated injection tubes or spindles, by means of which latter and the assistance of suitable pump or pumps the yarn is exhausted of air and impregnated with dye or other other suitable liquor, by drawing or forcing it through and ultimately extracting the superfluous liquor from the same.

Our invention includes one or more interchangeable plates or carriers, serving for the reception of hollow perforatedinjection tubes or spindles carrying the yarn to be treated, which plates or carriers are adapted to be placed in a treating tank, capable of being hermetically closed, in communication with a liquor and air pump or pumps and suitable supply pipes, in such a manner, as to subject the yarn in cop or other similar compact'form, to air exhaustion on the plates carrying it being placed into, and on being removed out of the treating tank, to liquor extraction, while when in the same it may be impregnated with dye or other suitable liquor or suitable gases through the action of a force or suction pump or pumps, either with or without preliminary air exhaustion or on hermetically closing the treating tank through the combined action of compressed air or steam and a suction pump and finally dried in the same apparatus by superheated air or steam. Near the lower end we employ, in the said treating tank, a perforated bottom and below the same a steam coil, to permit of heating the dye or other liquor in the treating tank. The sides of the said treating tank, a suitable distance above the perforated bottom, we bring, by suitable pipes, into communication with acirculating pump, the return pipe of which is in communication with the space of the treating tank containing the said steam coil. The plates carrying the yarn to be treated in cop or other similar compact form, are arranged to slide in grooves formed at the ends and in the perforated bottom of the treating tank at a short distance apart from the orifice of the pipes leading to the circulating pump, the said orifices being furnished with deflector plates, so as to divide the suction of the pump equally over the whole surface of the said plate or carrier, the upper ends thereof being supported by a rim furnished with a packing, thus forming a chamber between the said plates or carriers and the side of the treating tank. Above the said rims two other similar rims are formed a suitable distance apart from each other and pipes arranged between the same, communicating with an air pump. The said plates or carriers when lowered into or lifted out of the treating tank, by suitable appliances, bear against the said rims and thus form a comparatively narrow chamber, so that on communication being established between the same and the said air pump, the yarn on the plates or carriers is respectively subjected to air exhaustion and liquor extraction, which owing to the plate or carrier being gradually passed over said chambers and the comparatively small number of injection tubes or spindles thus brought in communication therewith successively, re quires only a small air pump, and efiects a more uniform exhaustion of air and extraction of liquor. The upper end of the said treating tank we furnish with a readily removable hermetically closing lid, by means of which the yarn in cop or other similar compact form may be dyed or otherwise treated under vacuum by exhausting the treating tank of air and afterward admitting and ciroulating the dye or other liquor through the same. In cases where the dye or other liquor is used in a very hot state, air or steam may be compressed onto the same whereby the action of the circulating pump is assisted and thorough impregnation of the yarn effected, or suitable gases may be used only. In connec- IOC tion with the said treating tank, we arrange a number of dye or other liquor supply cisterns, so as to permit of readily changing the dye or other liquor at will.

A number of the described apparatus may be arranged in connection with each other, so as to perform the various operations simultaneously and thereby save removing the cops from the plates or carriers.

Figure 1, is a longitudinal section of our apparatus on line AB of Fig 2, which latter is partly a side view and partly a vertical section, and Fig. 3, a plan in section on line O-D of Fig. 1.

In carrying out our invention and to remedy the aforesaid defects our improvements consist in the use of one or more, by preference four, interchangeable plates or carriers a, serving for the reception of hollow perforated injection tubes or spindles 19, carrying the yarn b, to be treated, which plates or carriers a are adapted to be placed in a treating tank 0, two of them being used in the treating tank 0, while the other two serve as reserve plates or carriers, to permit of exchanging the treated yarn for untreated yarn. In order to render the treating tank 0, capable of being hermetically closed a lid d, is employed, having on its under side a rim d, adapted to fit onto a packing o, placed into a groove formed in the flange of the treating tank 0, and secured thereto by means of hinged bolts 0 Near the lower end we employ, in the treating tank 0, a perforated bottom 6, and below the same a steam coil f, to permit of heating the dye or other liquor in the treating tank 0. The sides of the treating tank 0, a suitable distance above the perforated bottom e, we bring, by suitable pipes g, g respectively into communication with a circulating pump (not shown), the return pipe 71, of which is in communication with the space f of the treating tank 0, which is also furnished with an inlet and outlet pipe h, 7L2, having suitable valves (not shown).

The plates a, carrying the yarn b, to be treated in cop or other similar compact form, are arranged to slide in grooves a, furnished with a packing a and suitably formed at each end and near the perforated bottom 6, at a short distance apart from the pipe or orifice g, the latter being furnished in front with de fiector plates i, so as to divide the suction of the circulating pump (not shown) equally over the whole surface of the plates or carriers a. The upper ends of the latter are supported by a rim is, furnished also with a packing 03, thus forming chambers 9 between the plates or carriers a, and the sides of the treating tank 0. Above the rims 70, two other similar rims, Z and m, are formed a suitable distance apart from each other and pipes n and 0, arranged between the same, communicating with a suction or air pump(not shown).

The plates or carriers a, when lowered into or lifted out of the treating tank a, by suitable appliances, bear against the packing of,

of the rims k, l, and m, and thus form each space between, into a comparatively narrow hermetically closed chamber at, 0' so that on comm unication being established between the same, pipes n, a and 0, 0 and the suction or air pump (not shown) respectively, the yarn b, is subjected to air exhaustion, and liquor extraction, which owing to the plates or carriers a, being gradually passed over the chambers n, o and the comparatively small number of injection tubes or spindles I), thus brought in communication therewith successively, requires only a small suction or air pump(not shown), and eifects a more uniform exhaustion of air and extraction of liquor.

The yarn b to be treated is subjected toair exhaustion onthe plates or carriers a, being placed into and on being removed out of the treating tank 0, to liquor extraction, while when the plates or carriers a, are in their lowest position the yarn b can be impregnated with dye or other suitable liquor or gases through the action of a force or suction pump or pumps connected with the pipes g, (not shown) either with or Without preliminary air exhaustion, or on hermetically closing the treating tank a, through the combined action of compressed air or steam introduced into the treating tank 0, through pipe 0 0 connected with a compressor and a suction pump (not shown) and finally dried in the same apparatus by superheated air or steam or other hot gases if desired, introduced into the treating tank 0, through pipeo and permitted to escape through pipes g, g.

On hermetically closing the treating tank 0, by means of the lid d, the yarn b, in cop or other similar compact form may be dyed or otherwise treated under vacuum by ex hausting the treating tank 0, of air and afterward admitting and circulating the dye or liquor through the same by way of the pipes g, and chamber 9 In cases where the dye or other liquor is used in a very hot state, air or steam may be compressed onto the same whereby the action ofthe circulating pump (not shown) is assisted and a thorough impregnation of the yarn b etfected, or suitable gases may be used only.

In connection with an inlet h and outlet W, of the treating tank 0, We arrange a number of dye or other liquor cisterns (not shown) so as to permit of readily changing the dye or other liquor at will.

A number of the described apparatus may be arranged in connection with each other, so as to perform the various operations simultaneously and one treating tank may be connected with various supply tanks to permit of the successive application of various liquids to the same cops without removal.

Having now particularly described and ascertained the nature of this invention and in what manner the same is to be performed, we declare that what we claim is- 1. In combination, the tank having the ways ICC or bearings a therein and at a slight distance within the outer walls of said tank, the movable perforated yarn carrying plates adapted to said ways to inclose a space g between the outer tank walls and themselves, the pipes 9 leading through the outer wall into the space inclosed by the plates and the inwardly projecting ways and the return pipe leading to the tank lgetween the plates, the said plates having the cops on theirinner sides only, subspace the heating chamber f at the bottom of the tank, the coil therein and the return pipe h, connecting with the said heating chamber, substantially as described.
